Groundbreaking advance for fast connections
More mobility on rails

Goods and passenger traffic on trains is expected to almost double by 2035 compared to 2005.

Setting the course for the future

By 2030, investment in the expansion of railway routes will increase significantly – with up to $58 billion a year worldwide.

We prove our performance over the entire project route

Around the globe, contractors using Herrenknecht tunnelling technology are working to bring people closer to each other with direct train connections. 

New national and transnational rail networks for passenger and freight traffic are being created worldwide. Whether through mountain ranges, under rivers or beneath densely populated urban areas – tunnelling technology and experts from Herrenknecht are usually present at the key points. Together we use state-of-the-art technologies to build many kilometers of new, efficient railway tunnels every year. Highest technical and quality standards in combination with individual all-round service guarantee your project remains on time and on track economically over the entire distance. 

We connect what belongs together

Around the globe, hundreds of kilometers of tunnel tubes have already been built with our Earth Pressure Balance Shields, Mixshields and Hard Rock Machines for the expansion and new construction of underground railway connections. For your project this means:

  • vast experience and expertise
  • top technology of the highest quality
  • fully-customized, innovative solutions
  • smooth progress and expert troubleshooting
  • comprehensive service on- and off-site
  • close teamwork with all project partners
  • maximum reliability from start to finish

In short: we do everything to ensure your project runs as smoothly as possible while keeping to budget and to schedule.

Example jobsite overview

Herrenknecht tunnel boring machines push ahead to expand high-speed networks around the world, whether through mountain ranges, under rivers or beneath densely populated urban areas.

1
Vertical Shaft Sinking Machine VSM

The VSM is sinking a ventilation or rescue shaft for a railway tunnel to be built later – safely, quickly, and precisely. Equipped with a sinking unit and a shaft boring machine, the innovative machine can be used both in stable grounds and below groundwater.

2
Separation plant

Efficient and sequential processes separate and remove the excavated soil from the bentonite suspension – a mixture of water and thixotropic clay. The cleaned suspension is then transferred back to the slurry circuit.

3
Single Shield TBM

The Single Shield TBM allows safe tunnelling through all kinds of stable or loose rock. The tunnels are built using concrete segments which are manufactured especially for the project.
